What is FaceID?
Face ID is a unique facial recognition system developed and designed by Apple Inc. The system allows biometric authentication to provide access to a device, making payments, unlocking devices, and accessing other features within the device. Face ID relies on an intelligent mechanism that accurately maps the geometry of a face and stores the biometric information in the device. Whenever a user tries to unlock the device or perform a transaction, the system authenticates the individual by matching the biometric data with the one trying to access it.
